I can't check my voice mail

Try the following actions:

If you have more than one phone number associated with your BlackBerry® smartphone and you're trying to check your voice mail using a shortcut key, your smartphone calls the voice mail access number for your active phone number.
Check the voice mail for your alternate phone number.

You need a voice mail access number to check your voice mail. To obtain a voice mail access number, contact your wireless service provider or administrator.
